Create a blog/webpage with an FAQ, and direct people who ask common questions there.
Cosplay/experiment with weirder clothing (more comfortable/dramatic).
Get tattoos (probably temporary before permanent).
Strangely, some digital stuff.
Wear only swim briefs all through the summer, except when sun protection is needed. – Saves laundry and air conditioning. Requires great tolerance for being/looking weird.
